Anemia is a common blood disorder that occurs when there are fewer red blood cells than normal, and there is not enough hemoglobin transported to supply the body.

Hemoglobin. This is the part of red blood cells that distribute oxygen from the lungs to tissues in the body and carries carbon dioxide back to the lungs to be removed from the body.

Hematocrit. The measurement of the percentage of red blood cells found in a specific volume of blood.

Anemia is often a symptom of a disease rather than a disease itself. Anemia usually develops due to the presence of one of the following:

Excessive blood loss or hemorrhaging

Deficient production of red blood cells

Excessive red blood cell destruction

Both decreased production and excessive destruction of red blood cells

Sequestration (the pooling of red cells in the spleen)

Symptoms of Anemia

Most symptoms of anemia are a result of the decrease of oxygen in the cells or "hypoxia." Because red blood cells, as hemoglobin, carry oxygen, a decreased production or number of these cells result in "hypoxia." Many of the symptoms will not be present with mild anemia, as the body can often compensate for gradual changes in hemoglobin.

The following are the most common symptoms for anemia. However, each child may experience symptoms differently. The symptoms may include, but are not limited to:

The symptoms of anemia may resemble other blood disorders or medical problems. Because anemia is often a symptom associated with another disease, it is important for your child's physician to be aware of symptoms he/she may be experiencing. Always consult your child's physician for a diagnosis.

Anemia Diagnosis

Anemia may be suspected on a complete medical history and physical examination of your child, such as complaints of tiring easily, pale skin and lips, shortness of breath, or a fast heartbeat (tachycardia). Anemia is usually discovered during a medical examination through blood tests that measure the concentration of hemoglobin and the number of red blood cells.

In addition to a complete medical history and physical examination, diagnostic procedures for anemia may include:

Additional blood tests.

Bone marrow aspiration and/or biopsy. A procedure that involves taking a small amount of bone marrow fluid (aspiration) and/or solid bone marrow tissue (called a core biopsy), usually from the hip bones, to be examined for the number, size, and maturity of blood cells and/or abnormal cells.

Treatments for Anemia

Specific treatment for anemia will be determined by your child's physician based on the following:
